I totally understand your concern! Here are some fun ways I get my kids to eat healthy.
1)Fruit! Lots of fruit! Kids can't get enough of it. You have a sweet tooth? Then do something fun like dipping your bananas or strawberries in some chocolate syrup. That never fails.
2)Veggies a problem? I make it a game. Like, "I dare you to try these tomatoes! They are so good! MMMM!" If they don't fall for it, them just let them watch you enjoy yours. They'll come around.
3) Salads-My son loves salads now. He didn't wanna try them at first but then I got the crazy idea to add pepperoni slices in it! So he had a pepperoni salad! He loves it. Dressing? you can't go wrong with Ranch!
These are just some of the things that I do. My kids are generally healthy eaters, but the best way to get them to eat well is by setting the example. If you're not eating fruits and veggies, you're kids won't either. Try mixing it up. Also, if you add stuff in their dinners without telling them and they don't ask, and eat it all up...what they don't know won't hurt 'em!
